SMOKE-CONSUMING FURNACE.

SPECIFICATION forming part of Letters Patent N 0. 608,739, dated August 9, 1898.. Application filed November 22,1897. Serial No. 659,455. (No model.)

To all whom it may concern.-

Be it known that I, JULIUS \VEZEL, a subject of the King of Saxony, and a resident of Leipsic, in the Kingdom of Saxony, Germany, have invented certain new and useful Improvements in Smoke-Oonsuming Furnaces with Inclined Grates, of which the following is a full, clear, and exact description.

The present invention relates to improvements in furnaces having inclined grates divided into several steps, by means of which combustibles which develop great heat may be burned advantageously-i. 6. ,free of smoke and without damaging the grateand in or-. der to render the present invention more easily intelligible reference is had to the accompanying drawings, in which- Figure l is a longitudinal section of the furnace; Fig. 2, a planof same, partly broken away; Fig. 3, a vertical section of the middle damper; Fig. 4, a plan thereof; Fig. 5, a detail View of a poker to be used for said damper; Fig. 6, several combined grates of the kind as shown in Fig. 1.

A good draft is attained by arranging the flue-openings immediately behind the grate without leaving any intermediate space, said flue slanting upwardly from the end of the fire-bars d, as shown at f, Fig. 1, the part forming the bridge. Thus the gases of combustion are immediately led off in their natural direction without hindering the air-feed through the grates a, I), and (Z and the damper 0.

The grate may be constructed, as shown in Fig. 6, with more steps, so that the coal will be forced to pass two or more grates b c, Fig. 6, before it is completely consumed. Between the grates b and (Z and a and 5, Figs. 1 and 2, and c and d, b and o, (t and b, Fig. 6, respectively, a cooling-pipe system D, D, and D may be arranged, through which a continuous current of cold water is fed from the pipe E, the heated water of the system being led off in a suitable manner at F and applied to any desired purpose.

The cold water enters at D, is transmitted to D, and from D to D respectively, and therefrom led off at F.

The pipes D, D, and D are arranged immediately under the heads of the grate-bars b, a, and 0, respectively, crossing under the grate and cooling the latter at these parts. The draft of the air to the fire is increased by the cooling influence of the tubes.

The fire is worked inthe following manner: Before fresh fuel is introduced at A the material burning on Z) or Z) and c at the doors l3 and B, respectively, is pushed forward in the direction of (Z, and thus the fuel on grateb, being in the first stage of combustion, is pushed down one step of the grate. In order to effect this properly, the doors B or B, respectively, Fig. 6, which on removing the fire. must be fully opened, are provided with openings m, which may be closed by sliding plates h.

The openings at are opened by means of the poker, Fig. 5, the end A; of which poker is introduced into the fire, but no farther than the collar 92, thus preventing burning fuel from being moved toofar forward, but enabling sufficient movement of the same to cause it to pass from the grate b or b and 0, respectively, to the grate d as thoroughlyconsumed material, where it mixes with the air previously heated on its way through the grate and burns away, forming smokeless combustion-gases.

For observing the fire at the dampers B B, Figs. 1, 2, and 6, the same are provided with suitable peep-holes, Figs. 3 and 4., which re main always open. The arrangement of the said dampers as described obviates thenecessity of opening of same on raking the fire, and thus the falling out of fuel and the entrance of superfluous air is provided against.

The device maybe employed in connection with other inclined grates and can of course be carried out in any desired manner.

I claim as my invention 1. In a furnace the combination of a series of stepwisearranged inclined grates, having doors interposed between the steps, a waterpipe system extending around and between the steps, peep-holes and orifices through which to insert the fire-irons and means for preventing the fire-irons from being inserted too far into or between the steps, substantially as described.

2. In a furnace the combination of a series I11 testimony whereof I have signed my 0f stepwise-arranged inclined grates, having name to this specification in the presence of Io doors interposed between the steps, a watertwo subscribing witnesses. pipe system extending around and between J 1 5 the steps peep-holes and orifices through JULIUS WEZEL' which to insert the fire-iron and a fire-iron W'itnesses: having fast thereon a collar for the purpose ORWIN IIELBING,' substantially as described.
